PARIS (Reuters) - The European Aviation Safety Agency on Friday ordered emergency checks on some Boeing 737 jet engines, followed by regular inspections, in response to two Southwest Airlines engine blowouts including a deadly accident earlier this week.

The order expands a previous European directive, issued in response to the 2016 incident, and was issued in coordination with the U.S. Federal Aviation Administration, making mandatory a fresh recommendation from engine maker CFM International.

CFM is jointly owned by General Electric (GE.N) and France’s Safran (SAF.PA).
